Welcome to GTA5-Mods.com

@Punkman85
1) No, the optional changes only the color of the moon in the 3 Halloween weathers
2) The UFOs have a short LOD distance, so the player needs to be a little close for those to be rendered
3) The mod isn't paid/there's no paid content and the UFOs are there 24/7

@MonoChrome213 Maybe, those require a bit more work, unlike these where all I had to do was edit the textures

@Scooby271 The placements for aircraft carrier already exists. I don't know if, aside from TrainerV, there's any script that loads it. Either way, here's one that does that https://pastebin.com/1XSj5821
Just remember that the MP map needs to be loaded at startup from another script. In case the carrier isn't loaded, reload the script and then it should work
As for the scenarios, it's a lot of work, so I don't plan on doing that
@SnakeVenom33939 No, aside from these I don't plan on doing the other locations, mostly because of the interiors either being too big/small or not matching with the exterior
@Klemc They're all compatible

@misterstevemc Delete all the files inside "spgen7assets\dlc.rpf\x64\levels\gta5\props\lev_des\lev_des.rpf"

@amysteriouspa No

@CognizantDoor Download this and import it in spfixes/dlc.rpf https://pastebin.com/RWKKSa5j
Just note that I might add new archives in the future (if necessary) so you would need to make the same change again

@CognizantDoor I think it's caused by the trackid.gxt2
Comment out/delete the two lines related to "textpatch.meta" in the content.xml and it should work

@MrOutlaw1899 I think it's possible (but I don't know how)
The issue would be how to handle the reloading animations

@mrobey I don't plan on makingnew scenarios, since the mod only enables the already existing ones
@SuleMareVientu Can you make the Michael's bathroom window toggable from the ini?
I changed the flags of the prop itself in Fixes and Improvements so that it's openable and I would prefer to keep the original one loaded

@E3Im0 I don't know about Realism Beyond. As for GTA re-sized, I remember it changed some files which are also edited by this mod, but it should work anyway
